WEBVTT A WARMING TREND THROUGH FRIDAY. ALL RIGHT. LOWELL, THANK YOU. COMMON PRACTICE FOR PEOPLE TRYING TO GET FIT, TRACKING THE NUMBER OF STEPS THEY TAKE. IT USED TO BE BELIEVE THE MAGIC NUMBER TO A HEALTHY LIFE WAS WALKING 10,000 STEPS A DAY. SOME DOCTORS SUGGEST EVEN JUST A 15 MINUTE WALK AFTER WORK CAN HELP IMPROVE YOUR HEALTH. AND WALKING UP TO AN HOUR A DAY CAN BE GOOD FOR YOUR HEART AND HELP MANAGE STRESS. FOR OVERALL HEALTH, EXPERTS SAY THERE ARE PLENTY OF OTHER FACTORS AT PLAY. AND JOINING US WITH MORE INFORMATION IS MERCY MEDICAL CENTER'S DR. JONATHAN RICH. GOOD MORNING. GOOD MORNING. NOW I'M TOTALLY CONFUSED. YEAH. OK. WHAT DO I NEED? HOW MUCH A DAY? WHAT IS TOO MUCH? WHAT'S SORT OF THE GOLDILOCKS HERE, WHAT'S JUST RIGHT? I DON'T KNOW IF WE KNOW JUST RIGHT. GENERALLY FOR A LOT OF PEOPLE, PROBABLY DOING A LITTLE BIT MORE THAN WHAT THEY DO. THE THING I LOVE ABOUT THE 10,000 STEPS RECOMMENDATION IS IT GETS PEOPLE PAYING ATTENTION TO WHAT THEY'RE DOING. WE TEND TO FIND THAT PEOPLE THINK THEY MIGHT BE DOING MORE OR DOING LESS THAN WHAT THEY'RE ACTUALLY DOING SO THIS PUTS A NUMBER ON IT. SO YOU CAN SAY, WELL, I DID 2,000 TODAY. MAYBE I SHOULD DO A LITTLE BIT MORE. GET A FEEL FOR IT. SO THAT PERSONAL SENSE OF COMPETITION. WHAT'S THE SCIENCE BEHIND THIS 10,000? I'VE READ SOME STORIES ON IT THAT IT CAME OUT FROM WHEN THEY INVENTED PEDOMETERS, IT WAS A LUCKY NUMBER IN JAPAN SO THEY CAME UP WITH 10,000. BUT IT WORKS OUT TO BE ABOUT FIVE MILES A DAY WHICH IS NOT THAT UNREASONABLE TO DO IF YOU ARE JUST UP AND WALKING DURING THE DAY. SO WHEN YOU START KEEPING TRACK OF IT, YOU REALIZE IT'S NOT A CRAZY NUMBER. AND HOW OFTEN DO YOU GET TO DO 10,000 OF ANYTHING IN ONE DAY? THAT'S TRUE. PRETTY COOL. THAT'S A GOOD POINT. YOU LIKE THE TECHNOLOGY. IN FACT, YOU'RE WEARING THE TECHNOLOGY. YEAH, I GOT MY -- I'M AT MY 10,000 TODAY. IT DOESN'T TAKE MUCH TO DO IT. WHERE HAVE YOU BEEN ALL MORNING? I DID TAKE A RUN. SO YOU DO A RUN, YOU DO A LONG WALK AND THEN YOU THROW THAT ON TOP OF YOUR OTHER ACTIVITY, YOU COULD MEET IT. FOR THE AVERAGE PERSON, IT'S REASONABLE TO TRY SO SHOOT FOR. BOTTOM LINE IS? YOU GOTTA MOVE. ALL RIGHT. THANK YOU SO MUCH, DR. RICH. MY PLEASURE. HAPPY NEW YEAR TO YOU AND YOUR FAMILY. THANK YOU. YOU, TOO.
